USPP19260P2 - Scabiosa plant named ‘Vivid Violet’ - Google Patents

Abstract

A new and distinct Scabiosa plant named ‘Vivid Violet’ characterized by vivid violet flower color, large flower size, a low, mounding habit, continuous June to October bloom (in Canby, Oreg.), excellent mildew resistance, and excellent vigor.

Description

Botanical designation: Scabiosa spp.

Variety denomination: ‘Vivid Violet’.

Parentage: S. columbaria ‘Pink Mist’×S. anthemifolia ‘Giant Blue’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Scabiosa plant given the name ‘Vivid Violet’. Scabiosa is in the family Dipsacaceae. This new cultivar originated from a controlled cross between Scabiosa columbaria ‘Pink Mist’ (U.S. Plant Pat. No. 8,957), as the seed parent, and Scabiosa anthemifolia ‘Giant Blue’ (U.S. Plant Pat. No. 12,167), as the pollen parent. The resulting offspring were evaluated and the new invention was selected as superior.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Vivid Violet’. These characteristics in combination distinguish ‘Vivid Violet’ as a new and distinct cultivar:

• • 1. Vivid violet flower color;
  • 2. Large flower size;
  • 3. Low, mounding habit;
  • 4. Continuous June to October bloom (in Canby, Oreg.);
  • 5. Excellent mildew resistance; and
  • 6. Excellent vigor.

The new cultivar has been reproduced only by asexual propagation (cuttings and tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by cuttings and tissue culture using standard micropropagation techniques with terminal and lateral shoots, as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.
